Local display of thermal mass flow meters or controllers

30 April 2019

A new PCU series of controllers from AW-Lake are designed to connect with thermal mass flow meters or controllers to provide a local display of flow output.

Serving as a single- or multi-channel mass flow controller with up to four channels, the PCU instruments support multiple unit networked operations. A large backlit display offers easy-to-read views of process variables and programmed setpoints for each connected device on one screen.

The controller offers process control functionalities for batching, setpoint control, resettable dual totaliser and valve override control. Gas factor scaling allows users to set units to any fluid. Units are programmable to provide alarm status for high and low rates both visually and audibly.

Configurable from a keypad or using an RS-232 connection to a computer or PLC, the PCU controllers offer remote readout, setpoint control, and data acquisition capabilities. Built-in diagnostics ensure trouble-free operation by testing system operating status, memory condition, communication adapter status, display functionality, and keypad operation at every power-up.

PCU Series of Controllers are available in multiple configurations including panel mount. The PCU Controllers operate from 15 to 24 V DC and provide a variety of voltage or current outputs at operating temperatures ranging from 0 to 40°C.
